Palladium-catalyzed arylation of methyl (E)-4-(2-tetrahydropyranyloxy)-2-butenoate with aryl iodides and intramolecular cyclocondensation of the resultant 3-aryl derivatives affords 4-aryl-2-oxo-2,5-dihydrofurans in moderate to good yields.
钯催化 (E)-4-(2-四氢吡喃基氧基)-2-丁烯酸甲酯与芳基碘化物的芳基化以及所得 3-芳基衍生物的分子内环缩合在适度的条件下得到 4-芳基-2-氧代-2,5-二氢呋喃以获得良好的产量。
